Shimano GRX RD-RX812 11sp. rear derailleur - Unpacked

Description

On gravel, the pace changes fast, and you need shifting that can keep up. The Shimano GRX RD-RX812 11sp. rear derailleur helps keep the drivetrain composed even on rough surfaces. In the unboxed version, it goes straight onto the bike—no unnecessary extras.

Main benefits

This gravel rear derailleur keeps the chain more stable thanks to Shadow+ technology, so the ride is quieter over rocks and roots.

Support for a cassette with a largest sprocket up to 42 teeth gives you room for easier climbing gears, even with a loaded bike.

Direct mount simplifies installation on a compatible frame and keeps the derailleur closer to the cassette, where it’s better protected.
